[texts]An Overview and Analysis of Private and Public Key DNA Cryptography - K.Sireesha ,V.Srujana
with the growth of technological advancements, the threats dealt by a user grow exponentially. Hence security has become a critical issue in data storage and transmission. As traditional cryptographic systems are now vulnerable to attacks, the concept of using DNA Cryptography has been identified as a possible technology that brings forward a new hope for unbreakable algorithms. This paper analyzes the different approaches on DNA based Cryptography

Clouds are rapidly becoming a platform of choice for hosting increasingly complex application software and services. Among the attractive features they offer are elasticity and pay-as-you-go model, which allow businesses to gain access to vast computing resources with minimum upfront investment, and operational costs. Although a great deal of progress has so far been made with respect to the low-level technological underpinning of the clouds, today’s clouds are still considered to be insuffici...

The steganography method used is LSBinsertion technique. The encryption and steganographymethods are used subsequently along with two randomizationtechnique: one of XOR the encrypted text and another ofrandomized LSB insertion in any cover image...

We now explain the algorithm that Lempel and Ziv gave in a 1978 paper, and generally called LZ78. This is opposed to LZ77, an earlier algorithm which di_ered signi�cantly in the implementation details but is based on the same general idea. This idea is that if some text is not random, a substring that you see once is more likely to appear again than substrings you haven�t seen.

Whereas in proxy signature, on behalf of the original signer, proxy signer can generate the signature on an arbitrary message...
